in the keyconf structure, which makes it impossible to reuse the
indices that were used before entering D3.  Additionally, we overwrite
all the non-PTK keys with index 1, because the firmware only allows
one non-PTK key to be set.  This is bad, because when we resume, we
may try to set more than one key with index 1, which will obviously
fail.

To fix this, allow the callers to set a pre-defined index to use in
iwl_mvm_set_sta_key() instead of relying on the hw_key_idx value from
the keyconf struct (which requires overwriting it).  In normal cases,
the caller can pass STA_KEY_IDX_INVALID, which will cause a new key
offset to be chosen.  During HW_RESTART, we pass the offset that is in
use.  And during D3 entry, we pass the hardcoded indices we need to
use.

Additionally, don't clear the fw_key_table in D3 entry, so that the
flags are still set with the pre-D3 values when exiting D3.
